Book excerpt: This thesis presents a theoretical and experimental approach for the rapid fabrication, optimization and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. Developing non-invasive and reusable diagnostics sensors that can be easily manufactured will support the monitoring of high-risk individuals in any clinical or point-of-care setting. Sensor fabrication approaches outlined include silver-halide chemistry, laser ablation and photopolymerization. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. The sensors exhibited reversible Bragg peak shifts, and diffracted the spectrum of narrow-band light over the wavelength range λpeak ≈ 495-1100 nm. Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. Lastly, a generic smartphone application to quantify colorimetric tests was developed and tested for both Android and iOS operating systems. The sensing platform and smartphone application may have implications for the development of low-cost, reusable and equipment-free point-of-care diagnostic devices.

This book was released on 1979 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a study of four different hardened gelatin holographic recording materials are reported. These are the dichromated, diazo, diazo resin, and silver halide (sensitized) gelatins. The report concludes that of the four photosensitive processes studied, the silver halide (sensitized) gelatin process offers the most promising process characteristics. The silver halide gelatin process is a new holographic recording process that can be used toprepare phase volume holograms in hardened gelatin. The process uses a reversal bleach that dissolves the developed silver metal image while further crosslinking the gelatin in the vicinity of the silver image. Upon fixing and with dehydration of the resulting gelatin hologram, one obtains recordings similar to those produced by the dichromated gelatin process. This is accomplish with exposures on the order of 200 to 500 micron J/sq cm at 514.5 nm in a silver halide emulsion that has a panchromatic response. Furthermore, because the hologram has no silver halide present, the holgoram does not exhibit the printout phenomena characteristic of bleached holograms. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was conducted to study and improve the achievable holographic index modulation in dichromated gelatin suitable for producing high-quality holographic optical elements. Emphasis was placed on gaining a working knowledge of the chemical and physical processes involved in dichromated gelatin image production. The largest improvement in index modulation was achieved with the application of dicarboxylic acid salts. Index modulation could be increased by up to 150% per unit of light exposure over conventional processing methods by taking advantage of unipointly attached reduced chromium complexes. We confirmed the usefulness of the sol temperature as a measure of bulk cross-linking in gelatin. With polycarboxylic acids, index modulations of 0.16 were obtained in reflection holograms.
